MECHANICAL HEDGE-CLIPPER.

Specification of Letters Patent.

Patented Jan. 12, 1915.

Application filed December 20, 1913. Serial No. 807,830.-

To all whom it may concern:

Be it known that I, HARRY C. W'ALTER, a citizen of the United States, and a resident of New York city, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Mechanical Hedge-Clippers, of which tion.

This invention relates to mechanical clippers, particularly of the character adapted for clipping hedges and the like.

One object of the present invention is to provide 'a mechanical clipper, the drive mechanism of which can be attached to the body of the operator to be actuated by one hand while the clipper is applied with the other hand to the material to be out.

Another object is to provide a light, co1nbe entirely inclosed in a small casing easily carried about by the operator, and operated manually with one hand while the other hand is used for holding the clipper against the material to be cut.

The varlous further objects and advantages will more fully appear from the detailed description and the features of novelty consisting in the improved construction and combination of parts will be particularly pointedout in the claims.

In the drawing illustrating this invention, Figure 1 is a plan view ofthe improved mechanical clipper illustrating the means for attaching the gear casing to the body of the operator and the connection from the casing to the cutter blade. Fig.

,2 is an elevation of the gear casing with the cover removed illustrating the interior gearing and the mode of adjustment of the handle. Fig. 3 is a section taken along line 3-3 of Fig.2. Fig. 1 is an enlarged detail view illustrating the cutter blade and the means for reciprocating the same. Fig. 5 is a plan view partly in section taken along line 55 of Fig. 4. Fig. 6 is an end view of the cutter blade and its support and guide. Fig. 7 is a section taken along line 7-7 of Fig. 5, illustrating the disposition of the guide for the cross head.

Referring in detail to the drawings, the

for actuating the clipper is mounted in a light shell or casing 10 made preferably of aluminum or some other light metal. A freely removable cover plate 11 closes the the following is a specifica-' casing and renders the operating parts easily accessible.

The invention contemplates the attachment of the gear casing to the body of the operator, so that the gearing may be actuated by one hand while the otherhand is used to hold the cutter and apply the same to the material to be operated upon. In carrying out this conception, the rear side of the casing is provided with a bendable plate 12 attached thereto at or about the midwidth thereof adjustable to the contour of the waist or trunk of the operator to which the casing is attached. The plate may be of sheet metal and suitably lined with some soft cushingmaterial to contact the body.

Set screws 13: threaded in lugs 14 formed upon the casing may engage the plate at the corners thereof to adjust the same as.

1nay be required from time to time. The attaching means proper may consist of a strap 15 attached to an eye 16 formed on the caslng, the strap passing around the waist or trunk of the operator, and if it is desired, additional straps 17 attached to eyes 18 at the top of the casing may pass over the shoulders of the operator to the opposite eyes 16 previously described or to some other convenient point. The crank handle 19 extends from one side of the casing and is shiftable in and out as hereinafter described to suit the size of waist of the'operator. This handle is fastened. to a shaft 20 on which is splined a gear 21 meshing with a pinion 22 upon a shaft 23. The latter has mounted thereon preferably at its opposite end a pinion 24 meshing with another pinion 25 upon a stub shaft 26 passing to the exterior of the casing and adapted to be coupled to the flexible shaft 27. Fixed on the shaft 23 at an intermediate point thereof is a bevel pinion 28 meshing with another bevel pinion 29 fixed to a fly wheel 30, rotatably vertical plane extending laterally of the operator. By this arrangement of the fly wheel, the space within the casing is utilized with the maximum of economy and thecasing is rendered very compact and of a shape convenient to be carried around about the person of the operator.

The flexible shaft above described is coupled to a bevel pinion 31 journaled in the casing 32 and meshing with a bevel gear 33 mounted inthis casing. Extending from the latter is a hand grip 34: having a hollow interior communicating with the interior of the casing 32. In this hollowed out portion of the hand grip reciprocates a slide or tending from the hand grip;'"- The. cutter blade may be guided and held to the bar 41 by yokes 4:2 having teeth 43 engaging recesses formed in the bar 41 and provided with. guide screws 44 extending over a shoul- =der 45 formed upon the blade 38, and loosely engaging the latter so that'the-same may reciprocate within the yokes. Thus, when it-is desired to remove the blade, it is merely necessary to unscrew 'the i screws 44' and detach the blade from the cross head 35 which may alsobe accomplished through a screw connection. The guide way 46* for the slide 5 may conveniently consist of journals formed at the line of separation of the two halves of the hollow hand grip, thus facilitating the ease and promoting'the cheapness of construction.

For adjusting'the handletowardandfrom the casing to suit the size of the wa'ist'of the operator, the end of the shaft 20 is grooved and braced by a fork 4-6 which is clamped to the interior of the casing bya screw 4%? extending inward from the exterior of the casing through aslot 4:8. The screw may "be loosened and moved along the slot, thus carrying with-it the fork and thus actuating the shaft andhandle to adjust the same in the desired position relatively to the easing.

It will thus be seen that. T have provided an improved mechanical hedge'clippe r which may be carried about the person of the operator and driven withqone hand While the other hand is used for applying the cutter to the hedge. The various parts are so arranged and constructed as to promote the convenience of the operator and facilitate the ease of the operation with a device which is light, compact and eiiicient. v

Having thus described my invention, T claim as new and desire to secure by Letters Patent:
